l'ojwlfiwhom it may concern:

Be it known that I, ALOORN REoToR, of the city, county, and'State of New York, have invented a new and Improved .Telephone Attachment, of which the following is a full, clear, and exact description.

My invention relates to improvements in ttachments and the object of my mvention is to produce a simple and inexpensive attachment which can be applied to the ordinary telephone-receiver without destroying-or injuring any 'ofthe parts of the receiver and which will enable the sound to be conveyed to both ears'instead of to one.

'ere the receiver is applied to the ear, as usual, there is more or less confusion, owing ear is open to out-.

of the bearer who is using the instrument; and Fig. 9 is. a sectional View showing a modification which is'really the preferred form of the device. l

The receiver 10 is I has thecustomary earpiece 11. In,applying my apparatus the earpiece is first removed and the ring '12 .screwed to the receiver, as shown in 1 ig. 4, and the ring is preferabl y externally screw-threaded, so that the ear iece 11 can be screwed to the outer end of t -e ring, and thus no part of thereceiver is destroyed. The ring 12 has a diaphragm 13, which is raised from the receiver end to provide an air-chamber, and the function of this diaphragm is to support the sound-tube 14, which. registers with the earpiece-11 but the tube or channe 14 is preferably restricted at its outer end, as shown at 14*, so thatthe sound-waves are thereby diverted through the branch tube 15, which. leads the ring 12.

The ring 12 has a flange 1U", which may or may notbe a part of the diaphragm 13 and which holds the ordinary receiver-diaphragm in place. The tube 15 connects with a rubber tube 16 long enough to permit the second earpiece 11 on the free end of the tube to be conveniently applied to the second ear of the party using the instrument. The second mg device to apply to the second ear, connecting the two receiving parts by a tube, and restricting the'outlet to the first re.- e sound-waves will be in 5:11? checked and diverted to the second, I

d that hearing is rendered acute, and the telephone is conveyed to the ear. My invention is intended to carry out this idea in a simple and practical manner.

. With these ends in view my invention consists of certain features of construction and parts, which will be hereinafterdescribed and claimed. earpiece 11 is screwed to a cup 12, which Reference is to be had to the accompanyhas 'a tube 17, connecting with the rubber ing drawings, forming a part of this specificatube 16 and extending into the cup, the tube "tion, in which similar letters and figures of 17 having an upturned end 17 which comes referenceindicate corresponding parts in all the views. Figure 1 is a side elevation of my attachment as applied tothe ordinary receiver. ig. 2 is a plan view of the ring and attachment which is applied to the receiver. Fig. 3 is an end view of the receiver and attach.- ment. Fig. 4 is a broken cross-section through a part of the apparatus. Fig.5 is a cross-section of a slightly-modified form of the apparatus. Fig. 6 is a cross-section of tie receiving-cup, which is applied to the second ear. Fig. 7 is an end view of the l structure shown in Fig. 4. Fig. 8 is a broken very small opening through 1t, fromwhlch exeularged detail of a modified form of tlte 3 p. tends the dlverg mg -wall 18, so that the paratus, in which the second earpiece and sound-waves p'essmgthrough the small opencup are h ld t ti ally to the second ear 1 mg are then given a megaphone eirect. The

opposite the opening in the earpiece 11. It will thus be seen that a party can apply the first earpiece 11 to his ear and leave the part 1.2 dangling on the tube 16; but if it is necessary to hear better he can then apply the second earpiece 11. to his ear, and it will be found that he can hear the slightest sound.

If preferred, thering 12 can be simply a plain ring, with the tube 1 opening from the side; but it is far better to have the sound or venttube 14 restricted, and the best way to do this is shown in Fig. 9. Here a disk 18 is fitted in the tube 14, and the disk has a opening through the from the tube 14 out through .Y., ASSIGNOR To HIMSELF, DANIEL o.-

precisely as usual, and it T of the. operator, and

ta'chment so that the having at one end a disk 18 materiall 'ume of sound and the tube 15 to the By checking waves, as state vents the disa sion usual in te is first made. I

In some cases it is checks quite a large voldiverts the waves through second ea iece.

and diverting the sound- I find that it efiectually pree'eable snapping or concusephones when the connection desirable to have the at.-

second earpiece 11 will held at the second ear to provide for this the structure shown in Fig. 8 is suitable. As here illustrated, the flexible spring 19 supports the second earpiece and its cup 12, the spring sleeve 20 or equivalent be self-sustained and fastening device, and the sleeve fits over a supporting-stud 21 opposite end of the spring 19 is a The usted in a 1p 22, which is secured to the, cup 12*, and the on the spring 12.

os'ition of the spring in the clip can be fixe by the thumb--scre'w23. The structure I turns on the tube 15.

shown in 8 can readily be turned around,

so as to remove the second earpiece from the ear as the sleeve 20 turns readily on the stud 21 and the ferrule in the end of the tube 1 6 From the foregoing description it will be seen that I have which permits of 'theready ap lication of both earpieces to the ears of t e o erator and that'the sound is diverted, so t at the hearing is much more acute than y when asin- 'g'le earpiece is used. It will also that if it is desirable to use both earpieces continually the structure shown in Fig. 8 is well su-itedto-this purpose. v

Having thus ful y described my invention, I claim as new and desire to secureby Letters Patent' 1. The combination with a single receiver having an earpiece, of a ring interposed-bering adapted to be secured devised a slmple apparatus be noticed prising a dis tween the earpiece and the body of the receiver, a cup having an ear i'ece, and asoundtube leading from within t e ring to the cup.

' 2. The combination with the single receiver having an ear iece, of a ring interposedbe:

tween the b0 y of the receiver and the earpiece, said ring having means for supporting the diaphragm of the receiver, a cup carrying an earpiece, a flexible tube extend'in from the ring to the cup, and means within t 1e ring for}; diverting sound from the ring through the tu e.

3. An apparatus of the kind described comprising a ring adapted for attachment to a telephone-receiver, said ring having a sound-tube with a restricted outlet adapted to register with the opening of the earpiece of the receiver, means for securing the ring to the receiver, a branch tube leadmgfrom said vided'with a longitudinal sound-tube, of a branch tube lea ng from thesound-tube, and a checkin device in the sound-tube comhavin an o ening therethrough, anda bell-shaped evice leading from the said disk-opening.
